. 29 Claims.

This inventionrelates-to mountings for acoustic devices and moreparticularly to mountings for handset telephones adapted "tobe-supported on a vertical surface.

One object of the invention is to provide a mounting unit-for a handsettelephone which will enable easy removal of the handset from themounting by the user thereof while preventing accidental removaltherefrom under extraordinary adverse conditions.

Another object of the invention is to provide a mounting unit forahandset telephone which will maintain the handset in position on themounting unit under severe conditions such as encountered at battlestations or in gun turrets of fighting units in actual combat.

It is a further object of the invention to provide a mounting unit ofthe type described which is extremely rugged in construction and whichembodies a new and improved arrangement for facilitating replacing andremoving of the handset telephone from the mounting unit.

The foregoing objects and features thereof will be described hereinafterwith reference to the accompanying drawings, in which:

Fig. is a cross-sectional view of the mounting unit illustrated in Fig.ltaken along line 5-5 thereof with the handset 'unit mounted thereonasillustrated in Fig. 2, .and also shown in section.

Referringnow to the drawings, there isshown a mounting unit or supportillustrative of this invention, for 'a telephonehandset 32, whichmounting unit comprises a supporting base plate 6 and a casing orwell-shaped member generally indicatedas 1 which is preferably made ofcast brass formed inthe shape indicated to conform.

with the general contour of the handset "32. .A plurality of ,mountingholes .36 are .providedIin the base plate 6 forv securing the mounting,unit to a vertical wall or support notshown. The casing 1 is securelyfastened to the base plate 6 by means of a plurality of screws 8threaded into the casing I and comprises two parallel side wall portions-S'and i0 (Fig. 1), an upper curved wall portion H joining the twoparallel sides, and a lower curved wall portion l2 joining the parallelsides, thereby forming a cavity portion within the confines ofthecasing.

The upper curved wall portion ll continues outwardly away from the baseplate 6 and converges into an inverted cup-shaped member l3 providedwith two shoulder portions l4 and I5 joined by a bridge portion I6 thusforming a receiver receptacle. Shoulder portions l4 and I5 are formed ormoulded to fit the general contour of the receiver end I! of thetelephone handset 32 as is shown in Fig. 4, to thereby provide retainingmembers for the receiver end of handset 32 when it is in place in themounting unit. The bridge-shaped'member 16 is slightly raised from thegeneral contour of the inverted cup-shaped member 13, between theshoulders I4 and 15, to provide sufficient clearance for the raisedpartof the handle portion where it joins the receiver end I! of thetelephone handset 32 when it is removed from or inserted in place uponthe mounting unit in the manner shown in Fig. 3.

The lower curved wall portion I2 also continues outwardly from the baseplate 6 and con verges into anupright c p-shaped member l8 provided withtwo shoulder portions l9 and forming a transmitter receptacle.Shoulderportions I9 and 20 are formed or moulded to fit the generalcontour of the transmitter end 2| of the telephone handset 32, as isshown in Fig. 5, to thereby provide the retaining members for thetransmitter end of the handset ,32 when it is placed in the mountingunit. The central portion of the upright cup-shaped member l8 betweenthe shoulders 19 and 20'has been left open to permit the coupling unit23 and the cord 24, which extend from the transmitter end of the handset3 2, to protrude through the rather close fitting shoulder portions [9and 20 of the upright cup-shaped mfi ber I8.

Referring to Fig.2, thespring member 24 and th L-shaped stop-bracket2,5, are secured to the supporting base 6 by means of a plurality ofscrews .35 threaded into the base 8, Upper portion26 of the springmember 24is tensioned outwardly away from base 6 to engage the tip endofthe receiver cap i2! of the telephone handset 32 and the eby tends toforce the receiverend l? thereof into engagement with the shoulderportions l4 and 1.5 (Fig. 4 of the invertedcup shaped member [3 when thehandset is mounted in place on said mountinggunit. It should be notedthat the shoulder portions l4 and 31.5, which are formed toflt thegeneral contour of thei near surfaces of thetransmitter 17, as is shownin Fig. 4, prevent the upper portion 26 of the spring member 24 fromforcing the raised part of the handle portion where it joins the receiver end ll of the handset 32 into the space shown in Fig. 2 betweenthe raised handle portion and the bridge portion I6. Spring 24 at end 26thereof, also tends to force the handset 7 v vibration of the portion 28of the spring member 24. The spring member 24 is also bent back uponitself at 29 and extends upward and over the L- shaped end of stopbracket 25 to provide an engaging spring portion 30, which portion istensioned away from stop member 25 to engage the mouthpiece portion 3|on the transmitter end 2| of the handset 32 and thereby tends to forcethe transmitter end 2| thereof into engagement with the shoulderportions I9 and 20 of the upright cup-shaped member I8 when the handsetis mounted in place upon said mounting unit.

- In order to prevent the receiver end I! of the handset 32 fromovercoming the tension of the upper portion 26 of the spring member 24by inertia resulting from a severe shock or blow either on the mountingor on the handset a stop member 31 is provided which is adapted to beengaged by the receiver cap 21 of the receiver unit I I. -Ifhe stopmember 31 comprises a rod 38, preferably made from screw stock material,covered by a tube 39, preferably made from a phenol fabric product,which will withstand severe shocks or blows. The stop member 31 issuitably secured between the walls 9 and I0, respectively, for example,by means of washers 33 and screws 34 passing through the wall portions 9and ID, and threaded into the rod 38. H a

As is clearly shown in Fig. 2, the receiver end I! of the handset 32fits into the inverted cupshaped member I3 and the rear surfaces of thereceiver I'I are held into engagement with the shoulder portions I4 andI5 by means of the upper portion 26 of the spring member 24. Inaddition, the transmitter end 2| of the handset 32 fits into the uprightcup-shaped member I3 and the rear surfaces of the transmitter 2| areheld into engagement with the shoulder portions I9 and 2|] by means ofthe engaging spring portion 30 of the spring member 24.

. It should be understood that a force, such as caused by a bombexploding in the vicinity of the front or rear of th mounting unit,might cause the handset unit to momentarily overcome the tension of theend portions 26 and 30 of the spring member 24 but that the extent ofmovement of the handset 32 is limited at the receiver end H by stopmember 31 and is limited at the transmitter end 2| by stop member 25.Furthermore, the shoulder portions I4 and I5 of the inverted cup-shapedmember I3 and the shoulder ,portions I9 and 20 of the upright cup-shapedmember I8 prevent the handset 32 fromfbeing dislodged from the mountingunit. Although the force or explosion may be as high as 2000 footpounds, the handset unit 32 will neither become dislodged from themounting unit nor will any'of the parts thereof, including the handset,become broken, distorted or unusable. i Since the opening for placingthe handset unit 32 upon the mounting unit and for removing the handsetunit therefrom is limited by the distance between the shoulder membersI4 and I5 and the shoulder members I9 and 20 and since this distance isconsiderably less than the overall length of the handset unit 32, thehandset can only be placed upon-and removed from the mounting unit by aseries of definite predetermined movements, as will be describedhereinafter.

Referring now to Fig. 3, a description will be given of the placing ofthe handset 32 upon the 'mouhting unit.

In order to place the handset 32 upon the mounting unit the receiver endI! of the handset 32 is inserted at an angle of approximately 45 degreesinto the cavity of the mounting unit formed by the upper curved wallportion II, the parallel side walls 9 and It), and the invertedcup-shaped vmember l3, above the stop member 31. After they tip end ofthe r eceiver cap 21 has engaged the upper portion 26 of the springmember 24 and the tension thereof has been overcome by manual pressureexerted upon the handset 32 so that the spring member 24 is flat againstthe base 6, as is clearly shown in Fig. 3, the transmitter end 2| ofthe. handset 32 is in a position to passiclea'r of the shoulders I9 and23. Usingthe inner surfaces of the spring 26 and the uppercurved wallportion I I as and with continued manual pressure against the portion'ZBof spring 24, the transmitter end, 2| of the handset 32 1s manuallyrotated into the casing I until the mouthpieceportion 3| on thetransmitter end of the handset 32 engages the spring portion 36 ofthespring member 24 and compresses the'same. It is to be noted thatduring this rotation of the handset 32 in the above described movementthe transmitter end 2| passes clear of the shoulder portions I9 and 20of the upr ght cup-shaped member I8. Upon engagement with the springportion 33 of the spring member 24, and, as manual pressure is relievedon the'receiver end I1 of the handset 32, the tension in the springportion 3|] and that of spring portion 26 causes the mouthpiece portion3| to slide downwardly on the slanting surface of spring 30. Thus, whenthe pressure is applied to the transmitter end 2|, the pressure issimultaneously released fromthe receiver end I'I of the handset 32,consequently, the tension in the upper portion 23 of the spring member24 exerts a force upon'the tip end of the receiver cap 21 forcing thereceiver end I! of the handset outwardly away from the base 6 and causesthe rear surfaces of the receiver end I! to engage the shoulder portionsI4 and I5 of the inverted cup-shaped membe I3. Simultaneous with theaction of the upper portion 25 of the spring member 24 in'forcing thereceiver end ll of the handset 32 outwardly, the pressure exerted uponthe transmitter end 2| thereof on the slanting surface of the springportion '30 together with the downward spring pressure ex-' erted on thetip of the receivercap 21 causes the transmitter end 2| to engage thelower curvewall portion I2. When the pressure on the trans mitter end 2|of the-handset 32 is removed, the tension in the spring portion 3|)forces the rear surfaces of the transmitter end 2| to engage theshoulder portions I9 shapedmember I8. The handset 32 is nowin positionon th mounting unit and; cannot be dislodged therefrom even underextraordinary adverse conditions, however, the" handset 32 may be easilyremoved from the mounting unit by a series of movements along apredetermined path as willbe described hereinafter,

and 20 ;of the upright cup- 2,35 1,126 The handset 32 inay be easilyremoved rro'm be noted thatthe handset is-positioned inthe mounting unitwith the transmitter end 2| thereof and the receiver end I"! engagingthe shoulderp'ortions-IS and 20, and I4 and I5, respectively, underthepressure of spring portions 30 and 26, respectively. In order toremove the handset 32 from the mounting unit the handset is first movedin. a vertical direction with manual pressure applied to the receiverend I! thereof against the tension of spring 26. When the receiver cap21 has been raised sufficiently to pass clear of the st'opmember 30, thetip end of the receiver cap, has compressed the spring portion 26 untilit is fiat against the base 6. With the handset 32 raised to the maximumposition, that is, with the top portion of the receiver end l1 thereofengaging the inner surface of the casing l at the upper curved wallportion II and with the spring portion 26v compressed against the innersurface of the. base 8, the transmitter end 2| of the handset 32' may berotated about the bearings comprising the surfaces of the curved wallportion Hand the spring portionZG, and will pass clear of the shouldersI9 and 20, as is clearly shown in Fig; 3. When the handset 32 bat anangle of approximately 45 degrees with respect tothe base 6, thereceiverend I 1 thereof may be removed from the cavity in the mountingunit,

While one embodiment of the invention has been disclosed, it will beunderstood thatvar ious modifications may be made therein which arewithin true spirit and scope of the invention.
